What is Golang MCP Server SDK?
The Golang MCP Server SDK is a Go library that implements the Model Context Protocol (MCP), enabling developers to easily build servers that provide context and tools for Large Language Models (LLMs). It provides a standardized way for applications to expose resources, tools, and prompts to LLMs.
How to use Golang MCP Server SDK?
To use the SDK, install it using go get github.com/FreePeak/golang-mcp-server-sdk. Then, create an MCP server instance, define tools and resources, and add them to the server. Finally, choose a transport method (stdio, HTTP/SSE) and start the server. The provided examples demonstrate how to create simple echo and calculator servers.

The Model Context Protocol (MCP) is a standardized protocol that allows applications to provide context for LLMs in a secure and efficient manner.
What are the core concepts of MCP?
What are the core concepts of MCP?
The core concepts are Servers, Tools, Resources, and Prompts. Servers handle connection management, Tools let LLMs take actions, Resources expose data, and Prompts are reusable templates.
